Of the amounts in the above table, $17.4 million and $15.2 million are recorded in operating expenses for 2022 and 2021, respectively with the remainder in general and administrative. Our mine employees are also covered by workers’ compensation and such costs for 2022 and 2021, were approximately $4.9 million and $2.9 million, respectively, and are recorded in operating expenses. Workers’ compensation is a no-fault system by which individuals who sustain work-related injuries or occupational diseases are compensated. Benefits and coverage are mandated by each state which includes disability ratings, medical claims, rehabilitation services, and death and survivor benefits. We are partially self-insured for such claims, however, our operations are protected from these perils through stop-loss insurance policies. Our maximum annual exposure is limited to $1 million per occurrence with a $4 million aggregate deductible.
